PERMUTATIQN-PADLOCK.

SPECIFICATION forming part of Letters Patent No. 286,903, dated October16, 1883.

Application filed November 22, 1522. (1101101.) l

To all whom, it may concern.-

Be it known that I, XVINFIELD S. Orrnn1s- TER, a citizen of the UnitedStates, residing in the city of Newark, county of Essex, and State ofNew Jersey, have invented certain new and useful Improvements inPermutation- Locks, fully described and represented in the followingspecification and the accompanying drawings, forming a part of the same.This invention consists in the combinations of mechanisms herein shownand described, the object of the devices being to provide the bolt witha tumbler that shall be secured by a series of permutation-disks, and tooperate such disks by means of the combined indications of sound andfeeling.

I am aware that other locks have been devised to indicate, by means ofsounding devices, the position of certain parts of the mechanism, as inUnited States Patent No. 273,466,

and others; but my invention differs from them in the manner in whichthe different parts are combined and operated, as well as in theconstruction of certain parts-.as, for instance, the stop employed tofix the initial position of the operative spindle.

The nature and operation of the mechanism used will be understood byreference to the annexed drawings, in which Figure 1 isa side view of apadlock provided with my improvements, a portion of the devices beingremoved with the cover of the look, so that the view exhibits only thehasp A, the bolt B, the tumbler O, the permutation-disk D, and thespring 0 for operating the tumbler and bolt. Fig. 2 shows the inner sideof the coverand the remaining pieces of the lockworks, consisting of thecombined ratchetwheel E and permutation-disk D", the click F, and thesprings F and 1). Fig. 3 is a section of the entire lock in a transversedirection to Figs. 1 and 2, the parts shown in the section beingindicated by the dotted lines a: x in Figs. 1 and 2. Fig. 4. is anexternal side view of the entire lock, the bolt and tumbler beingindicated in dotted lines to express their relations to the other partswhen the bdlt is retracted. Fig. 5 is a vertical section on line 3/ '1in Fi 4 showin the )artsin the ri ht-hand J a 7 a z:

side of the latter figure. Fig. 6 is an edge view of the look at theright side, with the easing A removed. Fig. 7 is a similar view of onepermutation-disk, D. Fig. 8 is an edge View of the combined wheel E anddisk D, and Fig. 9 is an edge view of the stop G detached.

The bolt B is arranged to slide transversely in the casing A, and iskept in place .by a guide-pin, m, and rib n, the latter bearing againsta tail-piece, B, projected laterally downward from the bolt at its rearend, and having the tumbler O pivoted to it near the rib or. by a pin,70. The permutation-disks D, D, and D are mounted upon a spindle, l, onthe middle line of the lock, and arranged with their upper rims on alevel with the pin It. They areeach formed with a notch, r, to catch thetumbler, which is provided with abit, 8, extended across the rims of allthe disks, as shown in Fig. 5, and the disk D is connected with aspindle or shaft, 15, extended through the front of the casing A, forturning all the disks with their notches r toward the bit 8 upon thetumbler. A hand-wheel, I, is attached to the shaft 25 outside the casingby a screw, it, the shaft being made square, as shown in Figs. 4 and 8,or keyed. to the wheel, if preferred. The click-wheel E is shown inFigs. 2, 5, and 8 attached to the disk D, so that the latter partakes ofall the movements of the former, and serves to operate the other disksin the following manner when the hand-wheel I is turned: The disks D Dturn loosely upon the spindle l and are rotated solely by means of pins0, affixed at determined pointsand projected toward the adjacent disks.The disks are all separated by fixed collars o, and the disk D, havingthe spindle t and hand-wheel I attached, is provided with a pin, 0,projected toward the disk D and adapted to rotate the latter disk bycontact with its pins 0 when the disk D is turned by hand. The pins 0between the disks D and D are also adapted to engage one another whenthe latter disk is rotated by the pin 0, and the disks D andD may thusbe set in any desired positions by regulated movements of the hand-wheeland disk D. To effect such regulated movements of the disk D the latter.is provided, first,

with a stop-pin, a, and stop G, from which the series of regulatedmovements is gaged or started; and, secondly, with the ratchet or ICO .the groove for that purpose.

.tion-numbers used to open the look.

a esaooa click wheel E and click F, by which the operator can determinespecific movements of the;

wheel E without any visible dial or index. The stop G is shown in Fig. 5as a rectangular pin projecting through from the outside of the casingA, where it is attached to a thumb piece, H, for receiving the pressureof the finger. This thumb-piece is mounted upon a sliding shank, i,which is fitted to a socket, H, in the casing A, and aspring, p,pressing upon the inner end of the shank *6, serves to keep the stop outwhen not in use, as indicated in Fig; 6. hen pressed in by the finger,the stop enters a groove, formed in the wheels E and D adjacent to thecasing A, and serves to check the rotations of the said wheels at afixed point by means of a pin, a, inserted in By pressing upon the stopor piece H at anytime, and retating the wheel I in the proper direction,the movement may thus be checked at a predetermined point, and the stopthen released to permit further movements therefrom. To determine suchsubsequent movements from the initial point, the click-wheel E isfurnished with a specific number of teethsay twelve, as shown in thedrawingsand the pins 0 and o adjusted to coincide with certain twelfthsof the eliek-wheels movements. The three disks are therefore divided intheir construction into twelve imaginary sections, and the pins 0 and 0inserted in the central points of certain sections corresponding to acertain series of motions of the wheel I and disk D. The disk D is shownin the drawings in Fig. 5, provided with one pin, 0, and the disk D inFig. 1 provided with one pin, 0, shown in dotted lines, to engage withit, while two pins, 0, are shown with notched heads in the same figureto engage with the pin 0 upon the disk D. These pins are shown screwedinto tapped holes in the disks D and D, and twelve holes are shown inthe disks to permit the transfer of the pins to various positions forchanging the combina- Vith the arrangement of pins shown in thedrawings, the notches 1' may be brought into coincidence by turning thewheel I from the initial point secured by using the stop G, nine clicksto the left, five to the right, and then two to the left, the wheel Ibeing turned to the right after the bit is in the notches to withdrawthe bolt from the hasp. \Vh en the notches in the three disks are thusbrought to coincide with the bit 8 upon the pivoted tumblerQ, the bitfalls into the same, as shown in Fig. 1, and the bolt may be moved byturning the handle I and disk D to the right. The disk being fixed tothe spindle or shaft 1, and having a notch, r, in its periphery toengage the bit 8, moves the bolt by pushing the tumbler to the right,the bolt and tumbler sliding together, being pivoted at the pin it, andadvancing against the resistance of the spring 0, which is fixed at apoint in the casing below the rear end of the tumbler, and pressesagainst the widened end of the latter. This widened end spring-bearingat the rear end of the tumbler and tilting the front end of the tumblerupward, as shown in Fig. 4. When the bolt springs forward after theinsertion of the hasp, the bit is prevented from falling into thenotches 9" by a trippingpin, c, fixed in the casing behind the side ofthe bit, and arranged to enter a channel, 0, formed in the bit next thecasing.

In Fig. 4 the hasp is shown pressed all the way down, and the bolt as itis pushed back thereby. WVere it not for the 'pin 6, the tumbler wouldfall into the notches a when the bolt springs forward after being thuspushed back by the hasp,and the lock couldbe opened again by the turningof the knob I. The pin is fixed in the casing, so as to engage thechannel e as soon as the bolt commences to move forward, and is thusshown in Fig. 5, the view in Fig. 4 indicating the pin just before theend of the tumbler, and ready to engage it as it first moves. The lengthof the channel is proportioned to keep the tumbler elevated, as in Fig.4, until the bolt is entirely closed, when the tumbler falls upon therims of the disks, and the regulated movements have to be repeatedbefore the lock can be again opened. The combined tilting action of thespring 0 and the pin 6 thus secure a resetting of the combination everytime the lock is used, and the hasp is permitted to be selflocking.

The construction. and operation of my invention have been representedherein, for illustrative purposes,as applied to a padlock; but it isobvious that the same works can be used for a desk or chest lock.

Having thus fully set forth the nature and operation of my invention, Iclaim the same as follows:

1. The combination, with the casing A, of the click-wheel E, arrangedinside the'latter, and provided with pin a and connected by the shaft twith the handle I outside the casing, and the stop G, constructed topass through the casing to engage the pin a, and operated by pressurefrom the outside, substantially as and for the purpose set forth.

2. The combination of the notched disks, the sliding bolt B, the tumblerC, pivoted thereto, and constructed with the channel 6' in the sideadjacent to the pin 6, and the hearing for the spring 0, and the spring0 and the pin 0, inserted in the case so as to enter the channel 0 whenthe tumbler is raised, the

entering the notch r when the bolt springs forward, substantially as setforth.

3. The combination, with the notched disks rotated by pins 0, asdescribed, of the combined click-wheel E and notched disk D, the

wheel and disk being connected to hand-wheel I by shaft 1?, and themovable stop G, operating with a pin, as a, in the wheel E, to set the il i mechanism in its initial position, substantially as shown anddescribed.

4. The combination of the bolt B and tumbler O, constructed and operatedas described, with the notched disks, the combined clickwheel E, anddisk D, provided with stop-pin a, as described, and the stop G,operating I 5 through the casing of the look upon the pin a to adjustthe click-wheel to a specific position, substantially as herein setforth.

In testimony whereof I have hereunto set my hand in the presence of twosubscribing wit- 2o nesses.
